How the ketogenic diet increases fat burning
Q: you mentioned today that ketogenic diets are not different to creating an energy deficit but I have read that the ketogenic diet is superior to other diets for burning fat...
Without knowing exactly what was read or heard, it’s hard to address that specifically.
However, there is one aspect the ketogenic - and low-carb diets - that is often misrepresented.
In both diets, fat oxidation is dramatically increased than high-carb diets, meaning that more fat is burned for fuel (oxidised).
But it’s also true that more fat is stored on these diets, which is often not revealed.
Both diets have an increased fat and decreased carbohydrate intake, which the body responds to by using fat as the primary source of fuel.
This means that more fat is being used for energy, but it also means that more fat is being stored.
The outcome of fat loss or gain will depend on the balance between oxidation and storage, essentially still dictated by energy balance.
The opposite is true for high-fat diets - where we oxidise more carbohydrates and less fat than ketogenic or low carb approaches.
But this doesn’t mean we can eat unlimited carbohydrate because any excess calories will still be stored, be it as carbohydrate or fat.
The whole process is a bit like spending different notes - if the ATM gives you only $50 notes or $20 notes the denominations you use to purchase items will vary compared if you only had the other notes.
However, what you buy remains the same and the amount you have left depends on intake or expenditure.
